This would depend very much on the task. It is quite obvious that
for heavy floating point, especially double precision floating point
without tweaking, top of the line Pentium will be considerably

interactive computing, you will not see much difference, I think,
and for the really gigantic computing tasks you need to go to
multiple processors/multiple machines anyway.
